Embodiment Construction

[0022] In order to facilitate understanding of the present invention, the present invention will be described below with reference to the relevant drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] see Figure 1-3 , the present invention provides an anchorage nail guide plate connecting body, which has a male connecting body and a female connecting body. The overall height of the male connecting body is 4.0mm. Part of it is a cylindrical structure with an outer diameter of 4.3mm and a height of 1.5mm. The inside of the cylindrical structure has a groove structure that matches the head of the anchor nail. The diameter of the groove structure is 3.2mm. The cy...

Abstract

The invention belongs to the field of anchorage nail guide plate connectors, and relates to an anchorage nail guide plate connector. The anchorage nail guide plate connector comprises a positive connector and a negative connector, wherein a groove structure matched with the head of an anchorage nail is arranged in a column structure at the lower half part of the positive connector; the upper halfpart of the positive connector adopts a flat conical structure, the upper end of the flat conical structure is small in diameter, the lower end of the flat conical structure is large in diameter, andthe top of the flat conical structure is a platform; a concave structure matched with the flat conical structure of the positive connector is arranged in the negative connector; and the diameter of the platform of the concave structure is 10-20 microns larger than that of the platform of the flat conical structure. According to the anchorage nail guide plate connector disclosed by the invention, the negative connector can be accurately matched with the positive connector, the matching is stable, the connector is not liable to dislocate, and the connecting precision is guaranteed to be high.

Description

technical field [0001] The invention belongs to the field of anchorage nail guide plate connectors, and in particular relates to an anchorage nail-supported digital implant guide plate connector for edentulous and edentulous jaws or dentition defect cases. Background technique [0002] Implant restoration needs to determine the implant position, direction and depth before operation. The digital implant surgery guide plate makes it possible to design the implant position before operation and provide precise guidance during operation. The existing guide plate design for implant surgery can be supported by natural teeth in the case of a small number of missing teeth; while the guide plate for implant surgery for edentulous jaws with missing dentition, no matter whether it is made by additive manufacturing or subtractive manufacturing, it is supported by the mucosa The positioning effect of the guide plate is easily affected by the elastic deformation of the mucosa; for the imp...
